Electromagnetic fields at a mobile phone frequency (900 MHz) trigger the onset of general stress response along with DNA modifications in Eisenia fetida earthworms.

Research RF Safe Research Library Jan 1, 2017

This animal study exposed Eisenia fetida earthworms to 900 MHz electromagnetic fields at 10–120 V/m for 2 hours (with additional tests of longer exposure, modulation, and recovery). The authors report significant DNA modifications across exposure treatments and a decrease in probe hybridisation sites persisting after…

Radiofrequency electromagnetic fields and some cancers of unknown etiology: An ecological study.

Research RF Safe Research Library Jan 1, 2017

This preliminary ecological study examined whether RF-EMF exposure in Albacete (Spain) correlated with incidence of lymphomas and brain tumors from January 2012 to May 2015. Personal RF-EMF exposure was measured across 14 frequency bands using an EME Spy 140 exposimeter and compared with tumor incidence by…

Microwave frequency electromagnetic fields (EMFs) produce widespread neuropsychiatric effects including depression

Research RF Safe Research Library Jan 1, 2016

This 2016 narrative review proposes that non-thermal microwave/lower-frequency EMFs act primarily through activation of voltage-gated calcium channels (VGCCs), with calcium channel blockers reported to block EMF effects. It summarizes animal, occupational, and epidemiological literature and reports that exposures…

Effects of electromagnetic field (1.8/0.9 GHz) exposure on growth plate in growing rats.

Research RF Safe Research Library Jan 1, 2016

This animal study examined whole-body RF-EMF exposure (900 or 1800 MHz) for 2 hours/day over 90 days in growing male rats, compared with sham controls. Exposed rats showed greater weight and length increases and higher levels of several hormones and calcium. The study also reports changes in femoral growth plate…

Exposure to 900 MHz electromagnetic fields activates the mkp-1/ERK pathway and causes blood-brain barrier damage and cognitive impairment in rats

Research RF Safe Research Library Mar 19, 2015

This animal study exposed 108 male Sprague-Dawley rats to 900 MHz EMF (1 mW/cm2) or sham for 14 or 28 days (3 h/day). The authors report that 28-day exposure was associated with impaired spatial memory, BBB permeability damage, and ultrastructural changes in hippocampus and cortex. They also report increased mkp-1…

Influence of electromagnetic field (1800 MHz) on lipid peroxidation in brain, blood, liver and kidney in rats

Research RF Safe Research Library Jan 1, 2015

This animal study evaluated repeated 1800 MHz EMF exposure (5 × 15 minutes) on lipid peroxidation (MDA) in Wistar rats, including healthy animals and those with CFA-induced inflammation, with and without tramadol. The authors report slightly elevated MDA in blood, brain, and kidneys in EMF-exposed conditions,…

[Early and Delayed Effects of Radio Frequency Electromagnetic Fields on the Reproductive Function and Functional Status of the Offspring of Experimental Animals].

Research RF Safe Research Library Jan 1, 2015

This experimental animal study examined RF EMF effects on reproduction in CBA mice and on the morphofunctional status of their offspring under two exposure models. The authors report that repeated short-term RF EMF exposure (5 days, 10 minutes per day, 1.2 mW/cm2) affected pregnancy course, litter number, fertility,…

The effect of exposure of rats during prenatal period to radiation spreading from mobile phones on renal development.

Research RF Safe Research Library Jan 1, 2015

This animal study exposed pregnant Sprague-Dawley rats to a 900 MHz electromagnetic field during the first 20 days of pregnancy and assessed prenatal renal development. The exposed group showed reported histopathological kidney changes and increased caspase-3 staining suggestive of higher apoptosis compared with…

Exposure to radio-frequency electromagnetic fields from broadcast transmitters and risk of childhood cancer: a census-based cohort study

Research RF Safe Research Library Apr 1, 2014

This census-based cohort study in Switzerland examined modeled RF-EMF exposure from broadcast transmitters and childhood cancer risk using two cohort approaches. Across analyses, no association was reported for all cancers or childhood leukemia. Findings for CNS tumors were inconsistent, and the incidence density…

Effects of 900 MHz electromagnetic field emitted by cellular phones on electrocardiograms of guinea pigs.

Research RF Safe Research Library Jan 1, 2014

This animal study examined whether RF-EMF from cellular phones affects electrocardiograms in guinea pigs. Thirty guinea pigs were randomized to control (no exposure) or RF-EMF exposure (890–915 MHz; SAR 0.95 W/kg) for 12 hours per day over 30 days. The study reports no significant effects on ECG findings under these…

Assessment and comparison of total RF-EMF exposure in femtocell and macrocell base station scenarios.

Research RF Safe Research Library Jan 1, 2014

This study assessed and compared total RF-EMF exposure for a mobile-phone user in an office environment when connected to an indoor femtocell base station versus a conventional macrocell base station. Using a framework that combines near-field and far-field exposure, the authors report a 20–40× reduction in total…

The alteration of spontaneous low frequency oscillations caused by acute electromagnetic fields exposure.

Research RF Safe Research Library Jan 1, 2014

This double-blind, randomized, crossover study examined whether 30 minutes of near-field LTE radiofrequency exposure near the right ear alters resting-state brain activity measured by fMRI. The authors report decreased ALFF in multiple temporal and frontal/paracentral regions after real exposure compared with sham,…

Reactive oxygen species elevation and recovery in Drosophila bodies and ovaries following short-term and long-term exposure to DECT base EMF.

Research RF Safe Research Library Jan 1, 2014

This animal study measured ROS in Drosophila bodies and ovaries after short- and long-term exposure to DECT base RF (1.88–1.90 GHz; SAR 0.009 W/kg). The abstract reports increased ROS in bodies after 6 h exposure and in ovaries after 0.5–1 h exposure, with apparent saturation under longer continuous exposure. It also…

Effect of Bluetooth headset and mobile phone electromagnetic fields on the human auditory nerve.

Research RF Safe Research Library Jan 1, 2014

This randomized trial assessed short-term effects of electromagnetic fields from a mobile phone versus a Bluetooth headset on cochlear nerve activity during vestibular neurectomy in 12 patients. Bluetooth headset exposure showed no significant change in CNAP amplitude or latency. Direct mobile phone exposure was…

Whole brain EEG synchronization likelihood modulated by long term evolution electromagnetic fields exposure.

Research RF Safe Research Library Jan 1, 2014

This conference paper examined whether LTE radiofrequency EMF exposure affects whole-brain EEG functional connectivity.
